Not so very long ago when everyone used film Asahi Pentax lenses were considered right up with the very best in the world. Asahi Pentax, Leica, Zeiss, Nikon, Fuji were making top flight lenses that were regularly compared for quality.
I am in agreement with Kenspo that if Pentax are to stay in the game, and win hearts and minds, then the quality of the glass needs to recapture that former position. DFA* lenses, particularly the primes, should be aiming for that. So that when photographers compare they will know that Pentax lenses are right up with the best on the market.
To achieve that for modern sensors - and to future proof for 100MP plus sensors the design, glass, and build quality will need to be right up there.
That means big, heavy and for amateurs expensive. For professionals - not so much as there are depreciation and other tax advantages, and it is a tool to earn income with.
The reality is - professional fast glass has always been like that.
It is very good news that Pentax is reaching into this market again, and bodes very well for the future of the company.
